The PD controller should decide the role based on CC pin in the connector. Unfortunately the irq line for the TPS isn't hooked up which is a mode not yet support by the driver (some patches were submitted earlier this year[0]). So for now the PD controller is left out and peripheral mode chosen. -> USB1 instance - This is brought out to a USB TypeA connector on board. Therefore, add the required device tree support for the above in the board dts file. 0: https://lore.kernel.org/lkml/f714ee55-ef47-317d-81b9-57020dda064b@ti.com= /T/ Signed-off-by: Aswath Govindraju Signed-off-by: Vignesh Raghavendra [merge from vendor bsp, drop TPS6598 support, drop unneeded nodes, reword c= ommit message] Signed-off-by: Sjoerd Simons Tested-by: Martyn Welch --- Changes in v4: - Disable new usbss nodes by default in the dtsi and enable in the dts - Drop unneeded disabled nodes in board dts - Drop unneeded nodes - Enable usbss nodes - Small typo fix Changes in v3: - Rebased against current ti-next aka 6.2-rc1 - Add Martyn's tested-by Changes in v2: - Rebase against linux-next 20221220 arch/arm64/boot/dts/ti/k3-am625-sk.dts | 27 ++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am625-sk.dts b/arch/arm64/boot/dts/t= i/k3-am625-sk.dts index 4f179b146cab..6bc7d63cf52f 100644 --- a/arch/arm64/boot/dts/ti/k3-am625-sk.dts +++ b/arch/arm64/boot/dts/ti/k3-am625-sk.dts @@ -24,6 +24,8 @@ aliases { spi0 =3D &ospi0; ethernet0 =3D &cpsw_port1; ethernet1 =3D &cpsw_port2; + usb0 =3D &usb0; + usb1 =3D &usb1; }; =20 chosen { @@ -284,6 +286,12 @@ main_gpio1_ioexp_intr_pins_default: main-gpio1-ioexp-i= ntr-pins-default { AM62X_IOPAD(0x01d4, PIN_INPUT, 7) /* (B15) UART0_RTSn.GPIO1_23 */ >; }; + + main_usb1_pins_default: main-usb1-pins-default { + pinctrl-single,pins =3D < + AM62X_IOPAD(0x0258, PIN_OUTPUT, 0) /* (F18) USB1_DRVVBUS */ + >; + }; }; =20 &wkup_uart0 { @@ -464,3 +472,22 @@ partition@3fc0000 { }; }; }; + +&usbss0 { + status =3D "okay"; + ti,vbus-divider; +}; + +&usbss1 { + status =3D "okay"; +}; + +&usb0 { + dr_mode =3D "peripheral"; +}; + +&usb1 { + dr_mode =3D "host"; + pinctrl-names =3D "default"; + pinctrl-0 =3D <&main_usb1_pins_default>; +}; --=20 2.39.0
